Update part of screen

Is it possible to update concrete line of `ishell`?

I creating some application, which will return `results []*Result` slice to user. In my application hard background work should be done for each element of slice, so I want to notify user about current progress by sending new state of `*Result` item over `chan *Result` channel.

So, is it possible to update only concrete line of `ishell`, without re-writing all content of `results` slice?
